Why Does My Air Fryer Smell Like Burnt Food? Causes and Easy Fixes
You’re looking forward to a great meal, but a strong, unpleasant burnt smell wafts from your air fryer, ruining the moment.
That burnt odor is frustrating, but in most cases, it’s easily fixable. It’s usually a sign that your appliance needs a little attention rather than a major repair. Let’s explore the common causes and simple solutions to get your air fryer smelling fresh again.
What’s Causing That Burnt Smell?
1. Leftover Food and Grease from Previous Use
This is the most common culprit by far. Grease, oil splatters, and tiny crumbs that aren’t cleaned out can burn the next time you use the air fryer . The heating element gets hot enough to carbonize these leftovers, producing that burnt smell and sometimes even smoke .
2. Your Air Fryer is Brand New
A new air fryer can have a strong, chemical-like or plasticky smell during its first few uses . This is completely normal and is caused by “off-gassing” from the materials used in manufacturing and the non-stick coating (PTFE) . Manufacturers may try to burn this off, but it doesn’t always happen completely before the product is packaged .
3. The Time or Temperature is Too High
Cooking your food for too long or at a temperature that’s too high can easily burn the exterior. Fat and juices from the food can also drip down and burn on the hot surfaces, creating a persistent smell .
How to Fix That Burnt Smell
For a New Air Fryer: The “Burn-Off” Cycle
To get rid of the factory smell, you need to run a “burn-off” cycle before you cook any food .
- Wash It First: Start by carefully hand-washing the basket and any removable parts with warm, soapy water, and dry them thoroughly .
- Run It Empty: Place the air fryer in a well-ventilated area . Set it to a high temperature, around 400°F (200°C), and let it run empty for 10 to 15 minutes . Do this a couple of times if the smell is very strong .
This will burn off the protective oils and residue from manufacturing.
For a Used Air Fryer: A Step-by-Step Deep Clean
If the smell is coming from old, baked-on food, a thorough cleaning is the solution. Always unplug the appliance before cleaning.
1. Tackle the Removable Parts
- Remove the basket and drip tray.
- Fill the basket with hot water and dish soap and let it soak for about 30 minutes to loosen stubborn, burnt-on food .
- Use a soft sponge or an old toothbrush to scrub away the grime . Avoid steel wool or other abrasive materials as they will damage the non-stick coating .
- For really stubborn spots, make a paste of baking soda and water and apply it to the area, letting it sit for 15 minutes before scrubbing .
2. Clean the Interior and Heating Element
- You cannot submerge the main unit, but you can wipe down the interior .
- Use a clean, damp cloth to gently wipe the heating coil, removing any splattered grease .
- Be careful not to get the electrical components too wet .
3. Neutralize Lingering Odors
- Place an oven-safe bowl with a mixture of 1 cup of water and 2 tablespoons of white vinegar inside the empty air fryer.
- Run it at 180°C (350°F) for about 3 minutes . The steam will help loosen grease and neutralize the burnt smell . Afterwards, let it cool and wipe it out.
- For a fresh scent, you can also run the air fryer with a few lemon halves inside for a short cycle .

Frequently Asked Questions
Why does my new air fryer smell like plastic or chemicals?
This is called off-gassing. It’s a normal process where VOCs (volatile organic compounds) from the manufacturing materials are released when the appliance is first heated up . It should disappear after you run a “burn-off” cycle.
Can I put my air fryer parts in the dishwasher?
Many air fryer manuals say parts are dishwasher safe, but it’s often not recommended. Experts warn that dishwashers can be too harsh and can strip the non-stick coating on the basket, making it less effective and causing odors .
My air fryer smells burnt even after I’ve cleaned the basket. What else can I do?
You might be missing the heating element. Over time, grease splatters can burn directly on the heating coil. Gently wipe the heating element with a damp cloth once the unit has cooled down .
Can a burnt smell be dangerous?
The initial plasticky smell on a new air fryer is generally not dangerous at standard cooking temperatures . However, persistent burning smells from grease or food could be a fire hazard and should be addressed by thorough cleaning.
